I have just fitted a Megaflo heating system with a Worcester 40 boiler .I have 18 radiators ,of which 4 do not get hot. I have changed the pump to a larger variable speed one,but it made no difference.

hope you have g3 ticket for fitting megaflo this is a criminal act if not getting to your problem your balancing is out on system

Don't Blame your Megaflo as this only heats your Hot Water, you need to be looking at the system

I hope you have notified your local Authority Building Control Department as all Gas & Oil systems have to be notified to LABC and Documentation produced failure to do so could lead to prosecution under the Building regulations and could effect the Sale of the property in future
